How Online SAT Help Can Guide the Students in the Process of SAT Preparation?

First introduced in 1926 and owned, published and developed by the College Board, SAT is the standardized examination that every high school student who is eager to get into a prestigious college or university in the US meticulously prepares for. As an entrance test, the aim of this examination is to provide the colleges and universities with one common criterion that will help them evaluate the academic qualities of students and thereby simplify the process of college admission. In that sense, SAT can be described as a platform that provides the high school students with a fair chance to show the colleges the extent of their knowledge and how well they can apply it.

As the SAT is getting increasingly competitive with the participation of more and more students every year the need for additional help and guidance becomes equally indispensible. While studying on one's own might seem a satisfactory option at the first thought; a careful consideration would suggest that it is not a practical one. These days this additional outside help and guidance come largely from Online SAT Preparation Courses provided by some online tutoring companies. The tools that the online tutors use to communicate with the student during the tutoring sessions are crucial for an outstanding learning experience. A whiteboard is a virtual space where both the student and the tutor interact together to work on problems in real time. To make things more effective, some online tutoring service providers offer video chat where face-to-face interactions occur. Instant messaging systems are also used for chatting on important subject matters of the SAT. All these features help enhance learning with easy and open ways to communicate, making learning much easier.

In present times professional help for SAT preparation has become easily available and affordable online. Online SAT help is provided for a student in a one-to-one setting, at a time and place which is convenient for the student. Such an online course helps students in strategic planning, essay editing and other related tasks besides a diagnostic test. These diagnostic tests help identify a student's strengths and weaknesses for performance.

These online courses also provide guidance to the students for SAT preparation by giving them access to a variety of valuable study material designed by tutors who are highly professionals and who have an equally high level of competency in their area of expertise. Effectively trained for SAT preparation these online tutors specialize in detecting the strengths and weaknesses of the students and then utilize that knowledge to create tailor-made study plans suitable to their personal needs. These customized study plans provide highly adaptive, flexible, interactive and standardized guidelines that help students to smartly crack the SAT through online SAT Preparation programs. The mock tests that are conducted frequently familiarize the students with the format of the actual test, besides helping evaluate their performance. Thus, this tutoring style allows one to learn from the best, from the comfort and convenience of one's own home.

Essentially, the SAT evaluates the verbal and mathematical reasoning skills of the students and before appearing for SAT, students need to undergo special preparatory classes that train them in various aspects of clearing the tests. Particularly in this respect online SAT help can guide the students in the process of SAT preparation and bring success to their doorsteps.

Ammonia Solvay Process (Math Help)

Introduction to Ammonia Solvay process :

The ammonia-soda process (also called as Ammonia solvay process), it is the most important industrial process for the manufacture of soda ash (sodium carbonate). The ammonia-soda process was industrialized into new form by Ernest Solvay during the year 1860s. The constituents used for this production are readily available and cheap, example salt brine and limestone.

Ammonia Solvay process-based chemical plants now constructed about 3/4 of this deliver, with the rest being mined as of natural deposits.

Chemistry of Ammonia Solvay process

Ammonia Solvay process

Generally this processes consequences in soda ash ((Na2CO3) from brine (as a basis of sodium chloride (NaCl)) and from limestone (as a basis of CaCO3)).

In general progression is:

2 NaCl + CaCO3 ? Na2CO3 + CaCl2

The definite execution of this overall reaction is complicated. An easy explanation can be given using the four unusual, chemical reactions. In the first step, the CO2 is passed over a strong aqueous solution of sodium chloride (NaCl) and ammonia (NH3).

NaCl + CO2 + NH3 + H2O ? NaHCO3 + NH4Cl (I)

Industrially the preparation of Ammonia Solvay process is carried out by passage of concentrated brine solution all the way through two towers.

* In the first step, ammonia soap suds up through the brine and is captivated by it.

* In the second step, carbon dioxide bubbles up through the ammoniated brine and sodium bicarbonate (NaHCO3) precipitate out from the solution.


Basically the NaHCO3 is less water-soluble than sodium chloride. The CaCO3 in the limestone is partially converted to quicklime (calcium oxide (CaO)) and carbon dioxide.

CaCO3 ? CO2 + CaO (II)

The sodium bicarbonate (NaHCO3) that precipitate out in reaction (I) is clean out from the hot ammonium chloride (NH4Cl) solution, and then reacted with the quicklime (calcium oxide (CaO)) left in excess of from heating the limestone in step (II).

2 NH4Cl + CaO ? 2NH3 + CaCl2 + H2O (III)

CaO makes a tough fundamental solution. The ammonia from reaction (III) is cast-off back to the early brine solution of reaction (I).

The sodium bicarbonate (NaHCO3)that precipitate out in reaction (I) is then transformed to the last product, Na2CO3, by calcinations (160 - 230 C), producing water and carbon dioxide as byproducts.

2 NaHCO3 ? Na2CO3 + H2O + CO2 (IV)

The carbon dioxide from step (IV) is recovered for re-use.

Uses of Soda ash

* It is widely used mainly in industrial, and is sometimes used as an indicator of economic health.

* Applied in glass making processes, water treatment, making soaps and detergents

* Paper making, making sodium bicarbonate, to remove sulfur dioxide (SO2) from flue gases in power stations.
